Arquette Swelters In New York Box

The actor is spending two days above the world famous venue to raise awareness and funds for charity Feeding America.

He was chosen by the charity and sponsor Snickers because of his work feeding the homeless and hungry in California, and admits he jumped at the chance to help the cause.

Arquette invited WENN to join him as he kicked off his challenge and insisted - despite the 85 degree Fahrenheit (29.4 degree Celcius) heat - he was happy to be on show: "It is starting to get a little hot up here - but I had no hesitation saying yes."

He's confident he won't be getting bored in a box for two days: "I'm going on Facebook and blogging from here. Just passing the time hanging out. It's fun."

And he's even expecting visits from some celebrity pals, including Jennifer Aniston, who's shooting her new movie The Bounty nearby: "I think some friends are going to call by. (Jennifer) is in New York. I'm not sure if she's going to come along - she might just drive by."

Arquette is due to end his stunt on Wednesday (15Jul09).
